I believe your low sulfer diesel in the US is 10ppm, ours here is 5ppm. Heating oil is like 500ppm, and standard diesel (also called winter diesel) is 50ppm.

You could get away with a tank of 50ppm but as BMW has up'ed the power of there diesel engines the better the diesel fuel is required.

I believe Europe in now down to 1 or 2ppm, this is also partly why the US only gets the 35d and not the 40d, as the power is ramped up it requires a cleaner fuel. Its also makes it harder to meet the emission limits with 10ppm.

The waiver appears to only apply to non-road applications in NJ and clearly states to not use it in DPF equipped vehicles.

Here in the states all diesel sold for highway use is <15ppm sulfur (winterized diesel included).

The reason the US doesn't have a wider selection of diesels is because the demand doesn't justify the expense of certifying the power train with the EPA.

Ahh ok I sure hope this is the case, since from the above (thanks all) i clearly understand I must only use the low sulfur, my real fear was that the tanker really wouldn't have a conversation with the gas attendant and people would be pumping it without knowing. Of course if this was the case and my car was ruined (ie no signs posted) I'd guess it would make a class action. poor news reporting gave me paranoia ...

If the diesel in the US 15ppm I now understand why you have all the smog gear on the X5.

I have had the BMW diesels since 2003, and our diesel fuel back then was 50ppm, when it dropped to 10ppm BMW up'ed the output of the X5 when was the first release of the 2007 E70 3.0d, then came the 35d.

Then when the diesel fuel dropped to 5ppm the 40d came to Australia, then the LCI model. Basically they are all the same 3.0ltr motor with higher output being applied via mechanical inprovements (turbos, injectors, higher pressures etc etc).

I also know that New Zealand have the same diesel BMW's as us but they always had 20nm more torque than ours due to NZ being a cold weather climate, ours were de-tuned as being a sub-tropical.

I am supprised the US does not have 5ppm diesel. The US would use far more diesel than Australia so I cannot see how the cost would increase, the amount semitraliers you have in the US would out number the total amount of people living in Australia

not really sure why that is, I can say at all the pumps I could find so far the cetane is 40, yet others not in my area have been able to find higher grades. Thou I've only began to search for diesel. I can say so far the lines for diesel seem to be less. Hope I can get some gas soon thou...

The 40 cetane label is only showing what the minimum guaranteed cetane level. Cetane averages around 45 across the states.

You can find 'premium' diesel that is min 47 cetane at some stations. But don't just trust a premium label. Some states (like Texas) have no requirements for diesel to be called 'premium'. You need to call your state authorities to see if the 'premium' label means anything in your state. Then find out if any local distributors actually deliver high quality fuel by asking them what their claimed cetane is.
